Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range.
ETFE is effectively the high-strength version of PTFE, FEP and PFA. ETFE exhibits a high-energy radiation resistance and can withstand moderately high temperatures for a long period.
Combustion of ETFE occurs in the same way as a number of other fluoropolymers, in terms of releasing hydrofluoric acid (HF).
Applications: pneumatic panels, covering of electrical and fiber-optic wiring used in high-stress, low-fume-toxicity and high-reliability situation (aircraft and spacecraft), bonded with FRP as a thermoplastic liner and used in pipes, tanks, and vessels for additional corrosion protection, cable tie or cable wraps (ETFE has better mechanical toughness than PTFE).
ETFE is available in electrostatic coating powder, pellet, masterbatch and custom compound.
